Hi Paul,
Just completed a test of my build using a rebuilt 3.80 with the bug 1517
patch. [Note to WendyP -- this was using the rebuilt GNU make in the open34
module.]
The build now manages to include 4321 makefiles instead of 4305. So perhaps a
tiny amount of memory was saved by this patch, but not enough to fix the bug.
I'll try a test in which I try to include 10,000 empty files and see if that
triggers the bug. ... yes, I'm able to reproduce it. Here is a simple script
to generate 10K files:
#!/bin/ksh
i=0
while [[ $i -lt 10 ]] ; do
j=0
while [[ $j -lt 10 ]] ; do
k=0
while [[ $k -lt 10 ]] ; do
mkdir -p AAAA_$i/BBBB_$j/CCCC_$k
m=0
while [[ $m -lt 10 ]] ; do
touch AAAA_$i/BBBB_$j/CCCC_$k/DDDD_$m.mk
m=$((m+1))
done
k=$((k+1))
done
j=$((j+1))
done
i=$((i+1))
done
and here is a simple makefile:
ALL_INCLUDES := $(shell find `/bin/pwd`/AAAA* -name '*.mk' -print)
include $(ALL_INCLUDES)
.PHONY: all
all: ; echo "completed successfully"
BTW, the point at which the memory runs out is dependent on the length of the
path, which is why I use relatively long pathnames for the test.
The result of "make -R -k -d all" on an SV1 Cray UNICOS system within an NQS
batch job requesting 128 megawords (1GB) is

make: *** virtual memory exhausted. Stop.
As you can see, the memory is exhausted when 5000 files have been included.
Perhaps this will help you isolate the problem.
